Its ok to be wrong. Very few people on this board ever admit they made a mistake.
I love that you did research and spent time doing DD! Great stuff.
Most people want others to do the work for them. Dont stop searching. Dont stop double checking. This is YOUR DD and you must be satisfied with your research. Its refreshing to see.
I never have a problem with anyone double checking my work.
But there are nuances that are critical to making sure facts are correct and I usually watch for the nuances.
